WebThe Frequency Hopping Spread Spectrum or FHSS allows us to utilize bandwidth properly and maximum. In this technique, the whole available bandwidth is divided into many channels and spread between channels, arranged continuously. The frequency slots are selected randomly, and frequency signals are transmitted according to their occupancy. WebTheoretical analysis and simulation results show that the time–frequency domain characteristics of the KS-CSS signal are consistent with those of traditional DSSS signals.
